A 71-year-old woman was admitted with sudden onset of abdominal pain. CT scan image and symptoms showed an impending ruptured suprarenal abdominal aortic aneurysm therefore we performed an emergency operation. The abdominal aorta was replaced with a trunk prosthetic graft with four branches for visceral and lumbar arteries. The post-operative course was uneventful. Pathological examination showed that the aorta had severe atherosclerotic changes. The fibrous tissues increased in the aneurysmal wall which was not consistent with the normal aorta. Intima and media of the aorta everted into the aneurysm. These findings suggested that aneurysm was caused by a penetrating atherosclerotic ulcer.
